staining a chargless protein

Hi All,
Gee, this is a fascinating problem. I don't guarantee that it would
work, but you might try the zinc-imidazole stain. It is almost as sensitive
as Coomassie but is only stable for about 6 hours. Thus, you must photograph
the gel to have a permanent record. Check it out in:
Fernandez-Patron, C. et al. Biotechniques 12(4): 564-573 (1992)
"Reverse Staining of Sodium Dodecyl Sulfate Polyacrylamide Gels
by Imidazole-Zinc Salts: Sensitive Detection of Unmodified Proteins".
Have fun... -Shaun
